The operation of the apparatus thus far described is as follows: 1 c

' Initially, the box with a coated wrapper, either tabbed or untabbed,may be manually placed upon the form'block 9, 10, or automatically, asby mechanism of the general character described-in the application ofFederwitz and Bailey, Serial N 0. 40,769, filed July 1, 1925, whereinboxes are individually fed beneath the wrapping machine form blockstructure in timed relationwith the arrival of individual wrappers,either tabbed or otherwise. Regardless of what-manner the boxesandwrappers are fed and associated one with the other, a box B with acoated wrapper W adhering to its'bottom is moved by the form blockstructure 9, 10 into engagement with the upper surface of thelower formblock or platen 5, which yields and descends in opposition to spring 8asthe members 9 and lO'descend.
